S_AxisIN input

Input for specifying the axis to be controlled and monitored. By connecting the SafeAxisIn data item (provided by the Safety Module) to this input, a unique link between the function block and the corresponding axis is created and consequently a unique link between the axis and the controller.

Data type: SAFEDWORD

Connection: This input must be connected to the SafeAxisIn data item provided by the Safety Module which is controlling the respective drive or axis respectively.

Connect the input as follows:

  1. Left-click the Safety Module in the devices tree (in the 'Devices' window).

  2. Left-click the SafeAxisIn data item and hold the mouse button down. Drag the data item into the respective code worksheet and release the mouse button.

  3. In the appearing 'Variable' dialog, you have to declare a related global input variable. Either accept the variable name proposed by EcoStruxure Machine Expert - Safety or define/select another one.

  4. After confirming the variable dialog, the shape of the variable is added to the cursor.

    Drop it on the S_AxisIN function block input by a left mouse click to connect it directly on insertion.

Note that connecting the incorrect data item can cause hazards because the incorrect axis is controlled/monitored.

 WARNING

UNINTENDED EQUIPMENT OPERATION

  • Inspect and correct as necessary the assignment of the correct SafeAxisIn data item of the used Safety Module thus making sure that the correct axis is controlled.

  • Validate your safety-related architecture and thoroughly test the application.

Failure to follow these instructions can result in death, serious injury, or equipment damage.
